### Services

**UrlQueueService**: URL queue management (FIFO), duplicate detection via `visited()`
**DataService**: Access result persistence, iteration

**Implementations**:
- `UrlQueueServiceImpl`, `DataServiceImpl`: In-memory (default)
- `OpenSearchDataService`: OpenSearch backend (persistent)

# Incluyendo WSGI - Flask, Django, otros { #including-wsgi-flask-django-others }

Puedes montar aplicaciones WSGI como viste con [Sub Aplicaciones - Mounts](sub-applications.md){.internal-link target=_blank}, [Detrás de un Proxy](behind-a-proxy.md){.internal-link target=_blank}.

Para eso, puedes usar `WSGIMiddleware` y usarlo para envolver tu aplicación WSGI, por ejemplo, Flask, Django, etc.

## Usando `WSGIMiddleware` { #using-wsgimiddleware }

        private int indexToRemove = ABSENT;
        private int expectedModCount = biMap.modCount;

        // Calls to setValue on inverse entries can move already-visited entries to the end.
        // Make sure we don't visit those.
        private int remaining = biMap.size;

        private void checkForComodification() {
          if (biMap.modCount != expectedModCount) {

        if (generateAutoTestedSamplesTest.get()) {
            mainSources.asFileTree.matching {
                include("**/*.java")
                include("**/*.groovy")
            }.visit {
                if (!isDirectory) {
                    generateForFile(this)
                }
            }
        }
    }

    private fun generateForFile(file: FileTreeElement) {

Y el `items_per_user` mantendría su valor por defecto de `50`.

## Configuraciones en otro módulo { #settings-in-another-module }

Podrías poner esas configuraciones en otro archivo de módulo como viste en [Aplicaciones Más Grandes - Múltiples Archivos](../tutorial/bigger-applications.md){.internal-link target=_blank}.

Por ejemplo, podrías tener un archivo `config.py` con:

{* ../../docs_src/settings/app01_py39/config.py *}

- Validação de dados
- Anotação da API e documentação automática

E você só precisa declará-los uma vez.
